We consider a 10 km x 10 km simulation area, where 50 airborne nodes fly under the Gauss-Markov mobility model [1]} at 40 m/s. Each node has a 2 km transmission range. The number of flows considered are 1 and 3, where the source-destination pairs are randomly selected. The source and destination nodes use 4 antenna beams, whereas the remaining nodes use a single beam antenna. Since the source and destination nodes are connected via a multihop topology, the multipath-OLSR (optimized link state routing) protocol [2]} is used to compute multiple node-disjoint routes, which are used by both schemes. Here, we assume that each node knows its 1-hop neighbors through periodic neighbor discovery.
